## Description

The Fluke BK120 SmartTrace Breaker Finder is a tool for identifying circuit breakers in electrical panels and detecting voltage with the NCV mode. It is an essential device for electricians, homeowners, and maintenance professionals, to simplify electrical work, circuit tracing, and troubleshooting. The product includes a receiver that acts as the Breaker Finder and non-contact voltage detector, and a transmitter that traces to the receiver and also acts as a socket tester.

Review: Excellent for tracing circuits. - Excellent, circuit tracer. The transmitter is powered by the AC, so no batteries needed. The receiver works great, is easy to use. After plugging in the transmitter, make sure you hold the receiver perpendicular to the breakers. Scan all breakers once and ignore the beeps, as it’s automatically adjusting the sensitivity on the first scan. Then scan again and you’ll get very accurate locating information. I tried a cheaper scanner first that had a very nice digital transmitter with an OLED display. It required batteries and showed voltage and wiring faults, but it completely failed at tracing circuits. I was very careful to follow the instructions exactly. I highly recommend the few extra dollars for this Fluke, it was well worth the extra $20. I bought a box for it.
Review: Great Add to My Took Kit - Typical Fluke quality, which is to say, solid and well made. The unit works very well and is a big time saver. Sometimes it might read a nearby breaker to the actual breaker as the correct breaker, but once you've dialed it all in, it works well. Make sure you read the instructions completely, and hold the receiving unit parallel to the ground. I found the NCV mode of the unit to be ok, but not as good as my dedicated NCV unit. It works, mind you, but my smaller hand-held NCV is more convenient overall.

### ⭐⭐⭐⭐⭐ SmartTrace Circuit Breaker Finder
*by M***T on January 29, 2026*

There are many circuit breaker testers and many have extra items to test light sockets, alligator clips for wires, two pronged outlets, and a case. This one simply works well with a NCV tester which is CAT III unlike most of the others listed which are CAT II or not listed. While it was more expensive, despite a $20 reduction from the list price, it was the third one I tested with all the others returned. Save yourself some time and make sure you include this unit in your evaluation. I paid for this item and received no compensation from Fluke.
